What is short-circuiting of an electric circuit? An electric motor of 1.5kW power rating is
operated in a domestic electric circuit of current rating 5A. What would happen when it is
switched ON? Give reason for your answer.

A short circuit is an electrical circuit that allows a current to travel along an unintended path with no or very low electrical impedance. This results in an excessive current flowing through the circuit. The opposite of a short circuit is an "open circuit", which is an infinite resistance between two nodes.
Power=1.5kw
Voltage=220v(general voltage in domestic circuit)
Power=voltage ×current
1.5×1000watts=220×current
1500=220×current
Current=1500÷220
Current drawn=6.81amps(approx)
But it is operated on 5A circuit
So it leads to overloading and thus short circui
